Great sound for your conference room!

Installed a medium sized conference room and connected it to a Sony receiver. I turned it on and absolutely no distortion. If you're looking for uncompromised conference room audio, this is it. I am happy.

Pros
  • Acceptable
Cons
  • I'll write back later

Great concept --- incredibly difficult!

You'll spend more time figuring out how to hang this heavy speaker than the time you need to wire it up. This weight of the speaker will fall through your grille unless supported by cables from behind.

Pros
  • Satisfied so far
Cons
  • Interval

Revainrating 5 out of 5

Improves the sound in the conference room compared to the TV alone.

Ideal for our meeting rooms. You MUST have an amplifier between the TV and this one. Some of the simple ones here on Revain are good. Does not work directly from TV to speakers. If so, then you will hardly hear it. Get AMP!

Pros
  • Decent performance
Cons
  • Other Other
